We've got a cutthroat Billboard charts throwdown on our hands between two brand new singles from two of today's top pop stars.

So which artist has the better song?

We have our thoughts. Listen to the songs below - plus three other new singles from Drake, the Wanted and Baauer - and judge for yourselves.

Katy Perry
Single: “Roar”
Gut reaction: Yes, its true, Perry’s latest sounds suspiciously similar to Sara Bareilles’ spring single “Brave.” Consequently, this one probably won’t roar as loudly on the Billboard charts as singles from Perry’s past. But its still better than "Brave," namely because the lyrics are less on-the-nose empowering.Grade: C+

Lady Gaga
Single: “Applause”
Gut reaction: Hold the applause. Gaga’s latest may be another Madonna-style club jam, with just a touch of weird from some of Gaga’s hammy vocals. But without any cheer-worthy hooks, the single is more like a lowly understudy, unworthy in the company of her greatest hits. Grade: C-

Drake
Single: “Hold On We’re Going Home”
Gut reaction: After literally starting from the bottom with “Started from the Bottom” (the song’s chorus was basically glorified grunting), Drake actually hits a home run with this sexy, ‘80s-indebted love song, worthy of the high-caliber R&B Miguel and Frank Ocean have been putting out lately.Grade: B+

Just Blaze and Baauer
Single: “Higher”
Gut reaction: Even with featured guest Jay Z (who literally only says like five phrases), the new single from “Harlem Shake” hitmaker Baauer stands no chance of becoming another pop culture phenomenon. But that hardly matters--“Higher” is a heart-racing, higher-quality, hard-edged electrobanger.Grade: B+
